I often see joggers get to the corner and press that small button that is supposed to change the red light to green. Does it really work, can this one little button change the timing on that light? And if so, doesn't it affect the other traffic lights that are supposed to be synched with that light?

Scientists say this because they believe it has something to do with light spectrums that decieve the eye. New research into this phenonema has showed that the moon could just be a product of super charged light protons that float in the atmoshere. This theory adds weight to the suggestion that the moon landing was a hoax, and was falsified.

Ok lets assume that our sun suddenly turned into a black hole. (I know its not possible, so don't tell me so.) Because the location of the sun does not change it just centerizes to marble. How far would the event horizion (the point of no return) extend out. Past mercury, 2 inches?

The ones in the book to go by are:
x^2+y^2=25 which is a circle
y-x=1 which is a line
Where they intersect are the two solutions. I can't figure out how they graphed these in the book and none are in earlier chapters. Also couldn't find any websites that explain how.
How do you graph them?

Write an equation and solve: One leg of a right triangle is thee more feet than the other leg. The hypotenuse is 12 feet. How long is the shorter leg?
This is what I have:

1.x^2 + ( x + 3)^2 = 12^2
2.2x^2 + 6x + 9 = 144
3.2x^2 +6x -135 =0
4.now what? Quadratic?

And so make communication with others difficult?
Why not take the "bull by the horn" and change once and for all? The later you leave it the more difficult it will be. Mind you, we still use miles in UK, so we are far from perfect.
